Caustic Soda Flakes (NAOH)

Technical sodium hydroxide flakes, Sodium hydroxide flakes


Sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a synthetically manufactured substance. When dissolved in water or neutralized with acid it releases substantial amounts of heat, which may prove sufficient to ignite combustible materials.

The formula is NaOH. Sodium hydroxide is very corrosive. It is generally used as a solid or a 50% solution. Sodium hydroxide as a strong base, is considered from one of the most important industrial chemicals and strong absorbent of moisture. It is called caustic soda because it is highly corrosive in nature.

How to produce:

Technical sodium hydroxide flakes are obtained by evaporating of liquid caustic soda А grade and also it is obtained through the process of electrolysis of sodium chloride soluble in the electrolytic containers.

Safety and important points:

Due to its strong corrosive qualities, exposure to sodium hydroxide in its solid or solution form can cause skin and eye irritation, according to the U.S and Corrosive to metals and tissue.

keep the Caustic Soda Flake in tightly closed and properly labeled containers. Do not store caustic soda flake in aluminum container as flammable hydrogen gas can be produced. Caustic soda flake should be stored under dry and cold spaces well-ventilated in order to avoid dust forming and spreading.


We have two kinds of packing for caustic soda flake,

·    First, caustic soda flake packing is 25kg PP/PE bags in Jumbo Bag (per jumbo bag is weight is .250MT).

·   The next packing form is: 25kg PP/PE shrinking on pallet.


This chemical is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting. It is commonly found in commercial drain/ oven cleaners. According to the the FDA.

Sodium hydroxide is considered a direct food recognized as safe, where it serves as a PH control agent and follows good manufacturing guidelines.
